 +To Kim: remember to post guide here. 
 +Guide: To install lincan: 
 +First download the source files, either from the webpage or from github. 
 +Then run the ./build-lincan.sh, this will make everything we need and save it in the folder build-lincan 
 +The module needed by insmod(install module) is located in the _compiled folder, under modules.  
 + 
 +Now go to /etc folder and locate rc.local, here write the line: 
 +insmod [path to lincan.ko] hw=pcm3680 irq=7,11 io=0xda00 baudrate=250,250 (in this case, baudrate can be changed.) 
 + 
 +test the installation with rhdconfig.hako.xml. 
 + 
 + 
 +==== Grub problem - Statrup freezes in Bootmenu ==== 
 +If there has been an error with the computer for some reason, Grub is setup to ask the user to select which operating system it should load. The problem is a usb-keyboard is not recognised so it is impossible to start the OS. Rebooting does not help, the error will still remain. 
 + 
 +=== Solution === 
 +<note important>this solution assumes that you are running Ubuntu</note> 
 +Take out the Compactflash card, and mount it with a cardreader on your own computer. 
 + 
 +Open a terminal and navigate to the folder 
 +  /media/[user]/51e13800-d7fd-4da3-82ba-6442e5c08ca4/boot/grub 
 +[user] should be replaced with the username you are using. For example 
 +  /media/claes/51e13800-d7fd-4da3-82ba-6442e5c08ca4/boot/grub 
 +Now run the following command to edit the grub configuration 
 +  sudo gedit grub.cfg 
 +you can use any editor you like instead of gedit. 
 + 
 +Go to line 44 and change the line 
 +  set timeout=-1 
 +to 
 +  set timeout=0 
 +If it is not line 44 find this in the file 
 +<code> 
 +if [ "${recordfail}" = 1 ]; then 
 +  set timeout=-1 
 +else 
 +  set timeout=8 
 +fi 
 +</code> 
 +change it to this  
 +<code> 
 +if [ "${recordfail}" = 1 ]; then 
 +  set timeout=0 
 +else 
 +  set timeout=8 
 +fi 
 +</code> 
 + 
 +Save the file, put the card back in the computer and start it again. 
 + 
 +<note warning>Remeber to change the settings back again once the computer is started</note>
